Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of high-precision intelligent weighing system.
Specific embodiment
As shown in FIG. 1, FIG. 1 is a kind of high-precision intelligent weighing systems proposed by the present invention.
Referring to Fig.1, high-precision intelligent weighing system proposed by the present invention, comprising:
First acquisition unit, for acquiring the initial weight W of target item；First acquisition unit includes multiple acquisition moulds
The installation site of block, multiple acquisition modules is all different, can be from different perspectives with different location to the initial weight of target item
It is acquired, ensure that the comprehensive and reliability of collection result；And any one acquisition module includes multiple weight sensors,
It can further improve the precision to the acquisition of target item initial weight using multiple weight sensors, and multiple weight sensors can
It is acquired from different perspectives with weight of the different location to target item different location, further improves collection result
Accuracy.
Second acquisition unit is communicated to connect with control unit, for selecting different work according to the instruction of control unit
State is acquired the actual weight of target item；
Control unit is communicated to connect with the first acquisition unit；
Control unit obtains the initial weight W of target item by the first acquisition unit, and based on the initial of target item
Weight W divides weight range, and instructs control the second acquisition unit movement according to the weight range of target item.
Specifically: the second acquisition unit includes n Weighing module, is denoted as M1、M2、M3……Mn；In present embodiment, the
The installation site of n Weighing module is all different in two acquisition units, n Weighing module can from different perspectives with different location pair
The actual weight of target item is acquired, and is conducive to the accuracy and reliability that ensure its practical Weight acquisition.Further,
Any one Weighing module in second acquisition unit in n Weighing module includes multiple weight sensors, multiple weight sensings
The installation site of device is all different, and the setting of multiple weight sensors further improves acquisition precision, and multiple sensors
Different installation sites further ensure that the validity of collection result.
The first weight value W is preset in control unit1, the second weight value W2, third weight value W3；
As W≤W1When, show that the initial weight of target item is smaller, control unit delimit target item into first at this time
Weight range, and instruct the second acquisition unit of control using the first working condition；Since the weight of target item is smaller, then its is right
The requirement of the precision of sensor is higher, and the first working condition is selected to be conducive to improve the essence of the acquisition to the lesser target item of weight
Degree selects M in the first operative state1、M2、M3……MnWeighing module starts work, by selecting more Weighing module
To improve acquisition precision and validity to target item weight；
Work as W1<W<W2When, show that the initial weight of target item is moderate, control unit delimit target item and enters the at this time
Two weight ranges, and instruct the second acquisition unit of control using the second working condition；Compared to the article of the first weight range,
The article of two weight ranges is not necessarily to excessive Weighing module, therefore selects the second working condition, in a second operative state, selects
M2jWeighing module starts work, by reducing the Weighing module of work, can not only guarantee enough acquisition precisions, but also can be with
Reduce the waste of resource；
As W >=W1When, show that the initial weight of target item is larger, the target item of control unit delimitation at this time enters third
Weight range, and instruct the second acquisition unit of control using third working condition；Target item biggish for weight, is claiming
The frequency being interfered during weight is lower, then selects third working condition, under third working condition, selects M3iWeighing module
Start work, above-mentioned M3iWeighing module can not only guarantee enough acquisition precisions, but also can be to avoid the multiple weighing moulds of selection
The problem of wasting of resources caused by block works；
Wherein, 1≤i≤n/3 and i are integer, and 1≤j≤n/2 and j are integer.
Present embodiment is in the collection process to target item actual weight, using the scheme of secondary acquisition；
During one acquisition, after the initial weight for collecting target item, weight range is analyzed its initial weight and is divided,
And the acquisition scheme in the second collection process is selected according to the weight range of target item, when target item initial weight is smaller
When, it is worked at the same time using more Weighing module and its actual weight is acquired, mentioned by increasing the number of Weighing module
The precision of high collection result reduces influence of the extraneous factor to collection result and then reduces when target item initial weight is larger
The Weighing module of work avoids the waste of resource on the basis of guaranteeing collection result validity.Present embodiment passes through setting
The scheme of secondary acquisition effectively improves the accuracy to target item actual weight collection result, and acquired for the second time
The formulation of Cheng Fangfa and first time collection result tight association, further improve the accuracy of final collection result.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
